java:7 image appears to be mis-tagged

[celkins]

I would expect the java:7 image to contain/default to Java 1.7.

$ docker run java:7 java -version
java version "1.6.0_35"
OpenJDK Runtime Environment (IcedTea6 1.13.7) (6b35-1.13.7-1~deb7u1)
OpenJDK 64-Bit Server VM (build 23.25-b01, mixed mode)

I can't seem to reproduce:

$ docker pull java:7

Maybe I'm doing something wrong. Here's the behavior I'm seeing:

It works as expected if java:7 is the first image pulled (in a clean boot2docker VM):

$ docker run --rm java:7 java -version

However, if java:6 is pulled first (again, in a clean boot2docker VM), then Docker seems to get confused when it attempts to pull java:7:

$ docker run --rm java:6 java -version

That's really bizarre. 😕

Here's my own test on boot2docker 1.7.0-rc1:

After upgrading to Docker/boot2docker 1.7.0 I can no longer reproduce this issue. 🙈 🙉 🙊
